OFDM is a technique used in modern broadband wireless communications systems. To mitigate the effect of dispersive channel distortion in high data rate OFDM systems, CP is introduced to eliminate ...
Information is carried by changing the phase of the carrier. ->BPSK (Binary PSK): Uses two phases (0° and 180°). Very robust, but only 1 bit per symbol. ->QPSK (Quadrature PSK): Uses four phases (0°, ...
We provide 4 datasets including the popular modulation methods in 5G and 6G. The datasets can be obtained by linking https://mailnwpueducn-my.sharepoint.com/:u:/g ...
Moving wireless local area networks (WLANs) to the 5-GHz band is very appealing because of the leap in data rates from 11 or 22 Mb/s to 54 Mb/s. But, making the leap to 5-GHz also means the use of ...
Abstract: Ambient backscatter communication has emerged as a promising paradigm for ultra-low-power wireless systems. To support diverse IoT applications, backscatter communication should support high ...
Abstract: Orthogonal frequency division multiplexing with index modulation (OFDM-IM), which transmits information bits through ordinary constellation symbols and indices of active subcarriers, is a ...
The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...
